I see.
Well personally the only things I really care about are SQ and battery life. I'm not specially fond of RB and its annoying folders that are in the way of my navigation and that cannot be definitely suppressed.
Barely use the EQ as well so...

Sorry for double-posting but looks like this upcoming 'Sport' series it is not just one 16Gb model.
I've found p/n and EANs for the following;
4Gb - Black, Yellow, Red
8Gb - Black, Yellow, Blue, Pink, Lime
16Gb - Black
Still no pictures though...

Well there isn't much to see but here you go:

You'll find a number of stores who have listed the product without any pictures of the actual product, no release/stock arrival date as well.
